WINDOW VEN'rILaToR.

y, Application filed December 10,1927. Serial No 239,085.

This invention relates to ventilators for windows, automobile louvers, andV for any md all machines or appliances in or on which a ventilator of that character may be easily and, quickly applied to operative position; and, more particularly, to such a device which can bew applied to operative position on a window without interfering with the vertical movements of the window sash.

One of the objects of the invention is the provision of a ventilator which is adapted to permit a flow of air therethrough, and direct the air current upwardly, either in or out. Y i i f Another object of the invention is the provision of meansrfor resiliently retaining'in position the several panels of which the ventilator is composed. lStill another obj ect of the invention is the provision of panel-supporting brackets not only vequipped Awith means for resiliently clamping the panels, but also adapted for ready attachment tol window frame, automobile or any othermachine or appliance in or on which it is used. Y -v Other objects of the invention will be made apparent in the following specification, when read in connection with the drawings formin a part thereof.

In said drawings:

Fig. 1 is a perspective viewv of one side of a window equipped with my ventilator. n Fig. `2 is a side elevation, with a portion broken away, of one of the panel-supporting bracketsforming a part of the invention.

Fig. 3 is a section taken on the line 3 3 of Fig. 2. v

Now referring specifically to the drawings, in which similar reference numerals indicate like parts throughout all the views, 1 is a window frame, in which is mounted the usual sliding sash 2, equipped with the lower rail 3. A bracket 4 is provided for each of D the side frames 1, only one side frame being herein shown.

Each of the-brackets 4 is composed of a plate 5, made either of metal, wood, fibre, hard rubber, glass, or any other substance which can be used for such purpose, and, in the preferred form, as illustrated in Figs. 1, 2, and 3, is entirely covered with sheet rubber 6, and apertures 7 are provided near the rear edge of the bracket, adapted to screws or other members for fastening the brackets to the frame. Panel-receiving channels 8 are formed as a part of the rubber covering 6, either as separate installations, or integral with said covering. As indicated in the drawings the channels 8 are arranged in exact parallelism, the upper channel ter` minating just below the top end of the chans nel directly therebeneath. The channels .8 are delined by two side walls 9 formed of rubber, and are elevated considerably above the plane of the covering 6, as .clearly illustrated in'Fig. 3, Each channel is `provided at itslower end with a stop or abutment 10. In the the front cover sheets 6 are formed with the' channels 8 and the raised walls 9 molded thereon, and the sheets ai'iixed to the metallic plate 6 by vulcanizing process, glue, cement, or any othermethod. A plain cover sheetr 6 is similarlyapplied to the rear face yof the plate 5, and the loverlapping edges of the two sheets 6, around the peripheral edges of the plate 5, arejvulcanized together. lIt is of course obvious that, if found more desirable, the plate 5 maybe covered with two or more of the rubber sheets 6, the overlapping edges of the sheetsjoined together, and the channels 8 and the walls 9 formed apart from the sheets 6, and thereafter fixed in position. A n I have herein illustrated the brackets k4 as equipped with three of the channels 8, each adapted to receive panels 10. The panels are preferably oftransparent, opaque, hammered or Vcolored l glass, but may .be formed of any desired material, and it is obvious that any number of the panels ma) be used, fa bracket 4, having the necessary number of` channels, being provided.

Innuse,y the eXtreme end portions of the panels 10 arey placed in the channel v8, between the walls 9 9, the lattervbeing so spaced that the width of the channel 8 is slightly less than the thickness of the panel. ownward pressure upon the panel will cause the walls 9 9 to yieldingly spread preferred method of manufacture, y i

and permit the panel to be forced downwardly until its lower edge contacts the end wall or abutment l0. In this position the panel is securely but yieldingly retained in operative position, theV walls 9 9 exercising a constant pressure upon the panel, and thereby preventing any rattling which, under the influence of passing air currents, would be incident to any structure wherein the walls 9 9 were formed of wood, metal, or any unyielding material. It is obvious that, if the walls 9 9 ywere formed of wood by minimizing window casing.

they would soon become distorted by eX- posure to varied climatic conditions, and, if Jformed of metal, varying temperatures would result in such expansion or contraction as to either promote rattling noises or to dangerously compress the glass panels.y

For the foregoing reasons the utilization oi supporting brackets provided with panelgripping elements of elastically yielding material, is of great importance. By forming the Walls 9-9 of rubber, the panel 10 is; permitted a slight lateral-movement, therethe chances of breakage by a force applied to the side ofthe panel. In some installations it will be necessary for the panels to project intothe room, beyond the Under such circumstances, ifan occupant of the room should accidently violently contact a panel, or rest his -iveight thereagainst, the rubber Walls 9-9 would decrease the probability of rupture of the y panel andpossibility of injury to the occupant.

The rubber forming the walls 9-9 will endure indetinitely.- lVhen it loses itsrresiliency however, the fastening membersare removed from the apertures 7, and aV new bracket or brackets 4l immediately placed in position. j

From' the foregoing it will be obvious that I have provided a ventilator equipped with means automatically imposing a pressure upon the panels, irrespective of climatic conditions, including variations in temperature. As before stated such construction eliminates all disagreeable rattling of `the panels, greatly minimizes the chances `of "breakage thereof, and possible resultant bodily. injury, and permits substitution of parts, when necessary, Without the services of a skilled operator.

It will be noted that in both embodiments oithe invention I have shown the bott-om olE the front panel extending below the top of the rear panel, thereby preventing direct draft of air currents, andforcing said currents to move upwardly as they enter the room. y l i Leganes Modifications of the structure herein disclosed may be suggested to those skilled in the art, but my invention comprehends all embodiments falling fairly within the scope of the appended claims.

I claim:

l. A panel holder for window ventilators comprising a bracket adapted to be secured to a suitable support, a layer, of elastically yieldable material secured to the inner face of said bracket,=and a panelreceiving groove formed-in said material. 1

2. A panel holder for window ventilators comprising a bracket formed of a rigidfplate covered with elastically yieldable material having panel receiving grooves Vform-ed therein.

3. A panel holder comprising a bracket adapted to be secured to a suitable support, alayer of elastically Avieldable material secured to the inner face ing said bracket, and panel receivinggrooves formed in said covering. y l

5. A panel holder for Window ventilators comprising a bracket'adapted to be secured Y to a support, asoft rubber covering `enclosing said bracket, and panel receiving grooves formed in said coveringl and positioned laterally of said bracket.

6. A panel holder for window ventilators comprising a rigid plate covered with sott rubber having panel receiving grooves molded therein, substantially as and for the purposes set forth. Y l a 7. A panel holder for Window ventilators comprising a bracket having a body of elastically yiel'dable material mounted on one of its sides, and a panel receiving groove formed in said material. l

In testimony whereof I airix my signature.
